Reliable. Efficient. Drop by drop.

The Digital Enterprise portfolio for the water and waste water industry.

Water is the most valuable resource on our planet. That’s why efficiency and quality are top priorities for the water industry. These goals are becoming increasingly difficult to achieve as the expense of providing clean water grows in many regions, while at the same time operations have to be as efficient and economical as possible. The consistent, end-to-end digitalization of plants and processes helps the water and waste water industry meet these challenges.

Digital Enterprise

Digitalization throughout the water cycle

To enable the water industry to get the most from digitalization, Siemens developed the Digital Enterprise, a comprehensive portfolio of software and automation solutions. Processing all available data in a comprehensive data model makes it possible to optimally exploit the full potential of all systems. The result is a digital twin – a precise, virtual model of the plant that’s always up-to-date.

Benefits for greenfield and brownfield plants

The intelligent linking of data from different sources like sensors, water meters, and weather data is creating new opportunities to use water more efficiently – and therefore more sustainably – in industry, agriculture, and municipal utilities. A precondition is the end-to-end networking of system engineering, from commissioning to operation, maintenance, and ongoing process optimization based on a data platform – a merging of the virtual and real worlds.


The improved data quality and availability reduce project execution time in the real world. At the same time, the possibilities offered by simulation and modeling in the virtual world reduce both incalculable costs during the construction phase and ongoing operating costs.

Reaching your goals faster and more effectively

When greenfield plants are being planned, the combination of data from plant engineering and automation planning enables parallel work processes and sequences. This reduces the duration of the project while at the same time improving its quality.


Thanks to the integration of planning, engineering, and operation, the data acquired during the operating phase can be reused for engineering and supplemented with the latest operating data. The automatic updates to planning data during plant operation make it possible to always keep the actual condition of plants and systems in view when performing service and modernizations and to implement projects efficiently and effectively.

Systematically updated

Because their planning data is often unavailable in digital form or is incomplete or outdated, brownfield plants can benefit from digitalization. With the appropriate tools, even large and unstructured datasets can be read into a uniform database structure and verified. In addition, by integrating 2D and 3D data using appropriate tools, plants can be digitalized and linked to imported planning data in a database structure.


This is how the data can be verified and plant operators can obtain an up-to-date digital model of their plant.

Siemens Industry Suite for the Water and Waste Water Industry

Smart apps for greater efficiency and security of supply

The applications and digital services from the Siemens Industry Suite for water management provide higher transparency and therefore help identify optimization and savings potential for stronger security of supply. With the Siemens Water (SIWA) applications specifically developed for the water and waste water industry operators can optimize energy efficiency, avoid water loss, reduce contamination of water bodies and take predictive maintenance measures. 

Locating burst pipes with high accuracy

SIWA Burst analyzes high-frequency pressure fluctuations using intelligent algorithms. Detected pressure anomalies are classified in order to identify pipe breaks in real time. Damaged areas can be detected and localized with an accuracy of 20 to 50 meters.

Leak detection in water transport pipelines

SIWA Leak is a system for detecting larger and creeping leaks in water transport pipelines. As a supplement to existing control and automation systems, SIWA Leak continuously provides operating personnel with information on the status of the water transport pipeline, which – in the event of a leak – gives them a precise decision-making starting point for taking the correct countermeasures.

Leak detection in water distribution networks

SIWA LeakPlus – powered by BuntPlanet*– is an innovative solution for leak detection in water distribution networks. With the support of cloud computing, artificial intelligence, and hydraulic simulations, leaks can be detected easily and fully automatically and remedied at an early stage.

*Siemens cooperation partner

Cost-optimized pump operation in water supply systems

SIWA Optim is a solution for the intelligent, energy-optimized control of pumps and valves based on the latest system data and demand forecasts as well as daily updated energy prices. It allows operators to reduce energy consumption by up to 15 percent and ensure optimal security of supply.

Putting an end to clogged pump

The SIWA Pump Guardian is a secure IoT solution that prevents blockages and makes the performance of pumps and pumping stations completely transparent.

The solution helps detect and prevent clogged impellers, blocked pipework, and blockages due to single events.

Centralized sewer network control system to prevent flooding as a contribution to sustainable water protection

SIWA Sewer is a powerful and innovative sewer network control application that calculates the need for control interventions in drainage systems using optimization algorithms. In this way SIWA Sewer ensures optimum utilization of the sewer network, thereby preventing waste water from being discharged into natural waters. 

SIWA Sewer optimizes water treatment performance by stabilizing the inflow to the treatment plant so that the operator can run the facility more efficiently.

Preventing blockages

The SIWA Blockage Predictor, a Siemens MindSphere solution, evaluates combined sewer overflow behavior in real time, providing a better understanding of the system’s performance of any issues. 

This solution helps to identify if a sewer is blocked, or is not operating correctly, or if a CSO is soon to have operational issues. The analytics are embedded within a web application, enabling remote access on mobile devices or PCs and notifying users in advance of any issues.
